SPECIFICATION forming part of Letters Patent No. 581,717, dated May 4,1897. Application filed June 28,1888. Serial No. 278,413. (No model.)

T at whom it may concern.-

Be it known that I, GEORGE \V. HALL, a citizen of the United States,residing at Hermon, in the county of Penobscot and State of Maine, haveinvented certain new and useful Improvements in Typeriting Machines, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

The object of my invention is to provide a type-writer capable of rapidoperation and embracing many convenient and desirable features, mypresent invention being in some respects an improvement on the machineembraced by myPatent No. 364,343, dated June 7, 1887.

A denotes the frame of the machine, at the rear end of which is a smallupright bracket or frame a, supporting the rod b, on which are pivotedthe lower or transverse operatinglevers B and B. At the righthand end ofthe frame A is a depending bracket or frame a, supporting the rod 0, onwhich are pivoted the longitudinal operating-levers 0. Theseoperatil'ig-levers are all depressed by vertically-movable keys d,having operating-buttons D at their tops and provided with wings orprojections d to engage the said levers, the latter and the said keysbeing lifted by the spiral springs (4 attached to the outer ends of thesaid levers and to the lower parts of the frames or brackets to and a.The upward movements of the keys may be assisted by the springs (Z atthe bottom thereof. The keys (Z pass through holes in transverse and1011- gitudinal bars (1 and d", the former being at the bottom of theframe A and the latter at the top thereof, the said bars d beingsupported by the inclined bars a resting at their rear ends on the postsa.

E is the type-carrier, mounted on the rockshaft e, supported on centerscrews (1 tapped through depending lugs a at the rear of the frame A.The said type-carrier oscillates with the said shaft and has alengthwise-slid ing movement thereon, so as to bring any one of the typeof the said carrier into printing position to be struck by theimpressionhammer F. The rock-shafteis provided with arms e", Fig. 12,connected by links c with a rod 0 carried by levers e pivoted on the rod1), said levers being connected with the bracket or frame a by thelifting-springs a Then the rod (2 is depressed by means of a lug b onany one of the'levers B, the typecarrier will be rocked or oscillated asuitable distance to raise the desired line of letters into printingposition.

The type-carrier is connected with a slide g, Figs. 11 and 13, movablelengthwise in ways in the bar or guide A, Figs. 7 and 8, said slidebeing connected by a link g with an upright arm g of a rock-shaft 9having the horizontal arms 9 connected by links g with the levers gpivoted on the bar 0 in the depending bracket orframe a. The connectionbetween the slide 9 and the type-carrier is made by two cars 09,attached to said slide and arranged one at each end of the typecarrier,said ears embracing the rock-shafts on which said type-carrier slides.Thelevers g are connected together by rods 9 and g and are attached tolifting-springs The action of these lifting-springs may be supplementedby the adjustable spring 9 attached to the arm 9 of the rock-shaft g Therod g (near the free end of the long arms of the levers 9 is so placedas to be struck by all of the longitudinal operatinglevers C, so thatwhen any one of the said levers is depressed the shaft will be rocked,thereby imparting a sliding or longitudinal movement to thetype-carrier, the distance which the said type-carrier is moved being inproportion to the amount of movement of that one of the longitudinaloperating-levers depressed. As the vertically-sliding keys dare atdifferent distances from the pivotal points or fulcra of theoperating-levers B and (3, it will be obvious that uniform verticalmovements of the said keys will impart variable movements to the saidlevers, and the oscillating and sliding movements of the type-carrierwill therefore be different when different keys are depressed, so thatthe proper movements of the said type-carrier to bring any one of itstype in printing position in front of the impression-hammer are thusprovided for. The movements may be further varied or regulated by solocating the Wings 01 on the keys d as to have more or less lost motionbetween said wings and the operating-levers which they engage; and tosecure the proper location of these keys they may, if desired, be madeseparate from said keys, as shown in Fig. 33, so as to be verticallyadjustable thereon. These wings are, however, preferably formed integralwith the keys, as shown in Fig. 34.

As above described, the type-carrier is connected with or attached tothe slide g, and the said slide is provided with a series of projectionsor stops Q21, Figs. 11 and 13, to engage with fingers b projectingupward from the transverse operating-levers B through the opening insaid slide, said fingers being provided with notches or narrow portionsat their parts which normally come in the path of movement of the saidslide, so that the travel of the latter will be uninterrupted until astop comes in contact with a finger which has been depressed to bringits wider or stopping part in the range of a particular stop. The stopswill of course be so located relative to the stopping-fingers that anydesired length of movement of the slide can be effected before itstravel is arrested, and thus all of the necessary different lengthwisepositions of the type-carrier will be provided for. The fingers b strikethe stopbar A to arrest the upward movements of the levers B.

At about the center of the machine is a transverse bar or guide A whichreceives the hammer-releasing or trigger-operating slide f and thetransverse stopping-slide e, the latter having a loop 6 at its rear orinner end, embracing the rod 6 which connects the arms a of thetype-carrier. Between the said arms of the type-carrier is the arm a,rigidly secured to the rock-shaft e and thus moving therewith. The rod epasses loosely through a hole in the outer end of the arm 6 to permitthe type-carrier to slide freely back and forth on its supportingrock-shaft and relative to the said arm, and the latter, being rigidlyattached to the said rock-shaft and being connected with thetype-carrier through the said rod 6 causes the said typecarrier tooscillate with the shaft c when the latter is rocked by the mechanismshown in Fig. 12 and hereinbefore described.

The stopping-slide c" has a central slot or opening and a series ofinwardly-projeeting stops 6 similar to those of the slide g. Thelongitudinal operating-levers C are provided with dependingstopping-fingers 0 the lower ends of which, when the said levers are intheir normal or raised positions, are above the said stopping-slide, asshown in Fig. 7. The fingers c are normally entered into slots in thetrigger-slide f and are hinged so that they can swing to accommodate theshort reciprocating movements of the said slide f, the latter beingprovided at its front end with a projection or block f, of suitablelength to engage a cross-barf on the guide-bar A \Vhen any one of thelevers O is depressed, the stopping-finger 0 carried thereby will beforced downward through its slot in the trigger-slide f and the openingin the stoppingslide 6 so as to be in the path of movement of some oneof the stops on the said stoppingslide. Vihen the proper stop strikesthe depressed stopping-finger, the movement of the said stopping-slide ewill be imparted to the trigger-slide f until the block f on the latterstrikes the eross-bar f when the further movementof bot-h slides will bearrested. As the said stopping-slide e is connected with the rod 6 ofthe type-carrier by means of the loop 6 the oscillating movement of thesaid type-carrier will likewise be stopped, with the proper letter inprinting position, in front of the impressionhammer.

The trigger-slide is retracted by the spring f attached to a pin orprojection f 011 said slide and to the cross-barf or a projection onsaid bar.

The type hare secured in a segmental typeholder H, provided at its endwit-h curved ribs h, fitting in curved grooves in the typecarrier E, thesaid holder being secured in the carrier by the spring-pressed latches71 the ends of which enter holes in the said carrier. By withdrawing thesaid latches from the said holes the holder will be free to be removedfrom the carrier and may be replaced by another similar type-holder withdifferent type.

The types 7L are arranged to be driven against the impression-eylind erL by the hammer F and are surrounded by retractingsprings 7L3, arrangedbetween the inner and outer plates of the type-holder.

The impression-hammer F is carried by an arm f pivoted at its lower end.I is the ham mer'operatin g lever, the fuleru m of which is in alinementwith the pivot of the hammerarm, the said lever having a notch t,loosely embracing a cross-bar f on the hammer-arm. The lever I has anupwardly-extending arm t, to which is attached the impression-spring iand the said lever has a forwardly-extendin g looped trigger-engagingarm i surrounding the trigger it, (to be referred to presently,) and arearwardly-extending arm t'" to engage a stop 6 and thus limit themovement of the said lever when acted on by the spring The lever I isoperated to draw back the hammer from the transverse operating-1e vers Bthrough an actuating-frame consisting of the two arms 7;, pivoted on therod Z) and rigidly connected together by the rods 73 it the latter rodbeing engaged by projections or lugs b extending downward from the saidlevers l3. Attached to the said rods 7& 75 is a rigid arm 7;, to theforward end of which is pivoted the trigger 7;, normally pressed forwardin the looped arm t of the lever I by a spring .3 the said trigger beingnotched to form a hook or shoulder to engage the said arm 1. Thus whenone of the levers B is depressed and a lug or projection 19 strikes therod k the arm 7; will be forced downward, causing the hook or shoulderof the trigger it" to engage the arm of the lever I, an d as thecrossbar of the hammer'arm f is received in the notch t of the saidlever I the latter will be drawn forward, and thus retract the hammer Fin readiness for a blow. The trigger-slide is provided at its rear endwith a projection f which when the said slide is operated from thestopping-slide 6 as above described, will engage the trigger 7c, forcingthe latter rearward against the pressure of the spring k to disengagethe hook or shoulder 71: from the arm of the lover I, thus leaving thelatter free to be forced rearward by the spring 1' carrying with it thehammer-arm and hamm er, the latter striking the type which is inprinting position before it and thereby making the desired impression.

M is the carriage-supporting frame attached to the rear side of theframe A and having guidew ays m, in which the base-plate n of thecarriage N slides. The carriage N is provided with a rack n,with whichmeshes a gear-wheel 0 on the feed-shaft O, the vol utecarriage-actuating sprin J being housed in a box 0 on the under side ofthe wheel 0, said spring being attached to the shaft 0 and to a pin 0fixed to the frame or bracket Ct. Secured to the shaft 0 near its lowerend is a pawl or en gagementbar 0 having an inclined lower face, so asto be adapted to ride over the teeth on the upper face of theescape-wheel P, mounted loosely on said shaft, when the carriage is runbackward, but to engage said teeth and thus connect the said wheel withthe said shaft when the carriage is to be fed forward. The escapewheelis pressed upward against the said pawl or engagement-bar by a spring 0,attached to a lever oiwhich holds the said wheel on the lower end of thesaid shaft 0, said spring yielding somewhat when the carriage is runbackward to allow the escape-wheel to be depressed slightly, and thuspermit the inclined lower face of the pawl or bar 0 to ride over theteeth of said wheel, as above stated, said. spring holding said wheel upin engagement with the said pawl or bar when the carriage is travelingforward.

The eseapeinent lever or anchor 19 has an arm 19 which is engaged by anarm or project-ion k on one of the arms or levers 71: of thehammer-operating frame, so that at each movement of the said frame thesaid escapement-lever is moved to permit atooth of said wheel to passthe pallets of the escapementlever in the usual manner. Aretractingspringp is attached to the said arm 19 to effect the returnmovements of the escapementlever.

The carriage Nis provided with an arm 72 to which is attached a link ajointed to an arm a, attached to the carriage-returning shaft n,extending through the machine and having at its front end an arm a, towhich is pivoted at n the operating-handle a The shaft of is hollow, anda rod it" passes through it, the operating-handle a being jointed to thefront end of said rod. The said red at is provided with a pin at,extending outward through a slot in the hollow shaft 91 to engage aslide Q, having an inclined rib g, which is received in a slot in therear end of the lever 0 The slide Q is movable on the said shaft n andis pressed outward against the pin a by a spiral spring 71 arrangedbetween the said slide and a collar at, at tached to said shaft.

To the lower face of the escape-wheel P is attached a ribbon-feedingpinion p and below the said pinion and rigidly connected therewith andthus with the said wheel is a hub 11 having a groove which receives thefront end of the lever 0 so that the latter can, when desired, force theescape-wheel connected with said hub downward to entirely disengage thesaid wheel from the pawl or bar 0 the spring 0 having but a limitedthrow, so that when the forward end of the lever o is depressed it willnot prevent the escape-wheel from being disengaged from the said pawl orbar.

Thus if it be desired to run the carriage N forward for some littledistance without feeding it slowly forward by moving a space-bar or acarriage operating key the operator forces in the upper end of thehandle a as shown in dotted lines, Fig. 17, thus drawing the slide Q,connected with said handle, forward or inward and causing the inclinedrib q thereon, and which is in engagement with the rear end of the lever0 to depress the forward end of said lever and thus lower theescape-wheel out of engagement with the pawl 0 thereby disconnecting thesaid wheel from the feed-shaft, so that the carriage will be free to bemoved forward as far as may be desired by turning the carriage-returningshaft 72 by the handle a and when the said handle is returned to itsnormal position (shown in full lines, Fig. 17) the connection betweenthe feed-shaft O and the escape-wheel will be restored.

The movement of the carriage in either direction may be limited by stopsS, attached to a segment A on the frame A and having projections 8,arranged in the path of movement of the arm n of the shaft 01 and eitheror both of said stops may be adjusted on said segment by being attachedthereto by setscrews 5.

The impression-cylinder L is mounted on the carriage N. To the ends ofsaid cylinder are attached the heads 1", the hubs of which are tightlyfitted on the sleeves 7" T the latter being rigid with the milled buttonor finger-wheel r said sleeves having bearings in the uprights n of thecarriage N.

R is a rod or shaft fitted to slide endwise through the sleeves r W, andR is a toothed feeding or ratchet wheel by which the cylinder isnormally to be rotated to advance the paper when the carriage isreturned for a new line. The wheel R is loosely fitted on the sleeve 0",so that the impressiomcylinder with which said sleeve is rigidlyconnected may be turned backward, when desired, without rotating thesaid wheel. This detachable connection between the toothed feedingwheelfor the impression-cylinder and the said cylinder is one of theimportant novel features of my machine and is provided for in thepresent instance by forming the said in a slot r in said shaft, saidlevers'being connected to the disk 7' by the loops or brackets r.

WVhen it is desired to disconnect the impression-cylinder from thefeeding-wheel to permit said cylinder to be turned backward, the rod orshaft R is pulled outward by its head or button R as in Fig. 5, therebyrcmoving the segments 2 from the inner face of the rim of the wheel R,as clearly shown in Fig. 6; but when the said cylinder is to beconnected with the said wheel the said rod or shaft is pushed in, andthe toggle-levers will then be straightened, as in Fig. 6, forcing thesegments 1 into clutching contact with the rim of the feedingwheel.

The impression-cylinder is automatically rotated to advance the paperwhen the carriage is returned for a new line by means of the inclinedplate 2?, Figs. 1 and 3, placed below the guideways m of thecarriage-supporting frame M and in the path of the rigid depending armtof the pawl-carrier T, said pawl-carrier being provided with a pivotedspring-pressed feeding-pawl 25 Thus when the carriage is moved back bythe operator the arm 25 will engage the inclined plate 15, swinging thetop of the pawl-carrier to the left, Fig. 3, causing the pawl 15 to givethe desired amount of rotation to the toothed feeding-wheel R to advancethe paper held between the impression-cylinder and the feeding-roll Lbeneath said cylinder. As the carriage moves forward when a line isbeing written the arm 2? rides down the incline of the plate t, thuspermitting the pawl-carrier to swing back to its starting position underthe stress of the spring i pressing against the arm of the said carrier,the pawl riding idly back over the teeth of the feeding-wheel, and therotation of the latter being prevented by the detent F.

The pawl-carrier, operated by the incline t, always swings forward tothe same position, and the amount of the feeding rotary movement tospace the lines which will be given to the impression-cylinder willtherefore be determined by the backward throw of the said pawl-carrierunder the stress of the spring F. This backward throw of thepawl-carrier is regulated by an adjustable stop consisting in thepresent instance of a plate 25 pivot-ally attached by a screw 25 to thestandard a, which supports the pawl-carrier and which is attached to thecarriage N. This pivoted stopping-plate, as herein shown, is providedwith three holes i and it may thus be adjusted to three differentpositions by moving the said plate so that any one of the said holes isentered by the holding-pin t" in the standard 72-. The said plate t isof thin spring metal and is thus adapted to be sprung into and out ofengagement with the said pin and is provided with an operating-knob '6and with two steps or notches 23 The pawlcarrier T is provided with adepending stopping-arm t to engage either of the said steps or notches,or if the said plate be depressed to its lowest position said arm willbe stopped by contact with the side of said standard it, thus allowingthe pawl-carrier to have its full backward throw to give the longestfeed to the impression-cylinder and thus space the lines most widely.The inclined plate 15 is provided with an upturned slotted lip 6 Fig.16, by which the said plate is adjustably secured to one of thecarriage-ways m by a setscrew t Thus if short lines are being printedand the carriage is not to be moved to the end of its backward throw thesaid incline plate will be adjusted forward the proper distance tosecure the automatic feeding of the paper.

To prevent the carriage N from moving forward beyond a certainposit-ion, it may be stopped by means of a stopping-block t" on theincline plate 6, said plate being in the path of movement of a pin 91 onthe rackbar of the carriage.

Above the impression-cylinder and slightly separated therefrom is apaper-holding bar U, pivoted at one end to one of the standards or andentering a slot in the upper end of the other of said standards, whereit is re-- movably retained by a spring-catch u. The printed sheet isintended to run under the said holding-bar, which may be released fromits spring-catch at its free end and raised on its pivot, so as to bebrought down over the sheet should the latter fail to run under itproperly.

Beneath the impression-cylinder and the feed-roller L is the curvedpaper-guide 25 the upturned inner end or lip of which is pro vided withopenings,-Fig. 23, on the front side of said cylinder, through which thepaper may be seen, so that the operator can determine by casualobservation when the end or bottom of a page or sheet of paper isapproaching. The inner upturned end of the said paper-guide (which is ofspring metal) presses against the impression cylinder, and this causessuificient friction to enable the said cylinder to feed the paper afterthe end of the latter has passed upward beyond the friction of thefeed-roller L.

Asthe carriage-supperting frame is unobstructed at its ends, thecarriage may have any desired length of travel thereon, so thatinterchangeable impression-cylinders of different lengths may beemployed, if desired, and thus the machine may be used for printing longlines on wide paper.

Secured to the bottom of the frame A is a bar V, to which are fixed tworods 4;, on which are journaled the hollow shafts c, which rorate thespools v on whichis wound the inkrihbon c The shafts o are provided attheir lower ends with gear-wheels r rotated by a gear-wheel o meshingwith the ribbonfeeding pinion p, rotating with the escapewheel P, thesaid gear-wheel. n being carried by a swinging arm or lever r, to whichis attached a rod 1, by which the said arm 12 may be moved to cause thegear'wheel c to engage either of the gear-wheels r and thus positivelyrotate either of the ribbon-shafts r. The rod 12 is provided with twonotches n to receive a lat-ch r", Figs. 2 and 16, which will hold therod in position to retain the gearwheel r in engagement with either ofthe gear-wheels r said rod having at its outer end a head or knob r, bywhich it may be conveniently operated.

The ribbon-spools 'u are connected with the shafts c to rotatetherewith, but are adapted to slide up and down on the said shafts. Thissliding connection is herein shown as being effected by providing thesaid shafts wit-h grooves '0, entered by the points of screws o passingthrough the hubs of the spools, but may, if desired, be any ordinaryspline-andgroove connection. The ribbon-spools are su rrounded by cases7, attached toa cross-barn, supported by links 10, attached to the outerends of arms 10 fixed to a shaft 10 journaled in blocks w at the base ofthe machine, said shaft being provided with torsional springs 20 ofsufficient strength to hold the spoolcases W elevated. In front of theribbon, or between the latter and the impression-cylinder, is a shieldor plate w, attached to the bar '10 or to the spool-cases, or both, saidplate having an opening through which the type can print. If desired, asecond plate 10 similar to the plate 106, but on the opposite ortype-carrier side of the ribbon, may be provided, thus shielding theribbon between two plates. To one of the arms to is attached anoperating or depressing arm 10 to which latter is attached an adjustablestop or block w, secured to said arm by a set-screw u'. The said stop orblock is forced upward against the under side of one of the bars (1 bythe torsional springs 10 which hold up the spool-cases and connectedparts, as well as the ribbon-spools and ribbon. Thus by adjusting thesaid step or block up and down on the arm 11: it will be apparent thatthe ribbon (held edgewise verticallybetween the type-carrier andimprcssion-cylinder) will be sustained at different heights, so thatdifferent crosswise parts of said ribbon will pass in front of the typeto utilize the whole width of the ribbon.

Asthe type are arranged to print against the front side of theimpression-cylinder the printed matter is in view of the operator,excepting such part thereof as will be hidden by the ribbon-spool casesand ribbon and the plates w w, and to enable the operator to see thelast line or letter printedv it is only necessary for him to depress thearm '20 and thereby lower the said plates, the ribbon, and theribbon-spool cases out of the way. As soon as the operator takes hisfinger off the button at the upper end of the said arm the torsionalsprings 10 surrounding the shaft will return the parts to their normalpositions.

From the foregoing it will be apparent that the intermittingly-rotatingpinion p, eonnected with the escape-wheel, will impart a proper feedingmovement to one or the other of the ribbon-spools to wind the ink-ribbonthereon, and when the said ribbon has all vbeen wound on one spool therod n can be adjusted by the operator to disengage the gear-wheel o fromthat one of the gear-wheels '0 with which it has been in contact andengage it with the other of the said gear-wheels '0 to reverse themovement of the ribbon and wind it on the other spool.

The general operation of my machine is as follows: WVhen thetype-carrier is in its normal position it is depressed, as shown in Fig.7, so that the types of the top row are below the hammer and the lattercan therefore move without impressing any of the types, and when thesaid carrier is in this normal position any one of the levers B may beoperated to space the words by an ysuitable space bar or key, the saidlevers B actuating the carriage-feeding mechanism through the hammermechanism, as has been hereinbefore described. To print with any of thetypes in the left-hand row of types in the carrier, the latter needsonly to be lifted or oscillated upward to bring the desired type intoprinting position, no longitudinal movement of the type-carrier beingnecessary to bring the said types of the said left-hand row intoprinting position, but to bring any of the types excepting those of thesaid left-hand row into printing position both longitudinal and upwardmovements must be given to the carrier, the amount of these movementsbeing in proportion to the distance which the particular type to be usedis from the top and the left side of the carrier. The term left asherein used has reference to the position of the type-carrier in Fig. 1,or facing the operator. It will be apparent from the description of theconnection of the operating-levers with the type-carrier contained inthe early part of this specification that the transverseoperating-levers B will impart the upward or oscillating movement to thetype-carrier and the levers C longitudinal movement thereto. As the keys(Z by which these levers are actuated are at varying distances from thefulcra of the said levers, movements of dif ferent lengths may be givento said levers, and consequently to the type-carrier, by theuniformly-operating keys, as hereinbefore stated, the keys farthest fromthe fulcra of the levers of course imparting less movements to thetype-carrier than the keys nearer the fulcra of the said levers.

The levers B and O are arranged to cross each other, and when a key dthe wings of which engage both a lever B and leverC is depressedsimultaneous vertical or oscillating and longitudinal movements (or adiagonal movement, which is a resultant thereof) will be imparted to thetype-carrier, these movements being limited by the engagement of thestops of the stopping-slides g and a (connected with said carrier) withthe fingers b and c of the levers B and C. The depression of a key (Zwill also operate one of the levers B, the projection b on which willengage the rod of the hammer-actuatin g frame, and by depressing therigid arm it" of said frame will cause the trigger it to engage thelooped arm 6 of the lever I and draw back the said lever and thehammer-arm f, the cross-bar f of the said arm being in the notch i ofthe said lever, and when the type-carrier has arrived in printingposition the projection f of the trigger-slidef(the latter beingoperated from the stoppingslide 6 as hereinbefore described) will strikethe said trigger and release it from the arm i thus permitting the hairliner-actuating spring 1' to cause the hammer to strike the typewhich is in printing position before it and make the desired impression.In the meantime the arm k on the lever 70 of the hammer-actuating framehas engaged and moved the escapement-lever, so that the carriage hasbeen fed forward the proper distance for the next letter. It willtherefore be understood that when it is necessaryto impart both alongitudinal and an upward or oscillating movement to the typecarrier tobring a desired type into printing position (and this is the case withall of the types excepting those in the left-hand row of types in thecarrier) a lever C and a lever B must be operated, and in all instancesa lever B must also be operated to actuate the hammer and thecarriage-feeding mechanisms. As the carriage-feeding mechanism isoperated through the hammer mechanism, of course the hammer operatesidly when only alever B is operated to space the words. WVhen only anupward or oscillating movement is imparted to the type-carrier to printwith a type in the left rowof types therein, of course only one of thelevers B will be operated in addition to one of the levers B.

From the foregoing it will be apparent that by means of the two sets oftype-carrier-opcrating levers, arranged crosswise of each other, thetype-carrier may be moved in any desired direction in two planes orvertically and horizontally, but as these two movements are to occursimultaneously the real movement of the type-carrier will be theresultant of two forces, or a diagonal movement. It will of course beunderstood that the typecarrier may be arranged to slide up and down ina right line instead of rocking or osoillating up and down, if desired,and instead of sliding horizontally the type-carrier may rock oroscillate horizontally, the essential point being that it must bemovable in two different planes, and whether these movements are rockingor sliding ones is immaterial so far as the principle involved isconcerned.

In the machine shown by my patent hereinbefore referred to thetype-carrier, movable in two different planes, was operated by tworocking bars or shafts, each having a set of fingers orlevers, all ofwhich moved together when one finger or lever was depressed by the keyby which it was engaged; but in the pres ent instance the levers of eachset are all me"- able independently of each other.
